Accommodates up to 16 disk drives installed within the DS5020 enclosure
with attachment support for up to six EXP520 expansion units, providing modular
and highly scalable storage solutions that range up to 112 TB physical storage
capacity

The DS5020 disk system is designed to deliver up to a two-fold IOP performance
increase over the current-generation DS4700 offerings and represents the eighth-generation
architecture within the midrange disk family.

The DS5020 is designed to provide high performance and high availability
and comes with 2 GB cache memory (1 GB per internal RAID controller) as a
base feature. A cache memory upgrade to the 4 GB cache memory (2 GB per RAID
controller) feature (#2070) is available as an initial plant order feature.
There are no cache memory upgrades available as field (MES) features for the
DS5020.

The DS5020 gives you choices of either four or eight 8 Gbps FC host ports;
or four 8 Gbps FC ports and four 1 Gbps iSCSI host ports for connectivity
to the SAN-fabric or host servers.

If a customer desires, an additional four 8 Gbps FC host ports (two 8 Gbps
FC ports per RAID controller) option is available by ordering the Two Dual
8 Gbps Host Ports card feature (#2080) during an initial plant order for the
DS5020. This feature includes four shortwave 8 Gbps SFP transceivers to populate
the ports.

Also available as an initial plant order option is a Two Dual 1 Gbps iSCSI
Host Ports card feature (#2081). This feature provides four 1 Gbps iSCSI host
ports (two 1 Gbps iSCSI host ports per RAID controller) with an RJ-45 connector
for each port. Feature 2081, together with the base FC host ports, enables
customers to have both FC and iSCSI host connectivity.

The iSCSI host ports feature (#2081) is mutually exclusive with the optional
FC host ports feature (#2080). Decisions as to the number of host ports and
host port options must be made during initial plant order of the DS5020. There
are no host port options available as field (MES) features on the DS5020.

The DS5020 and EXP520 can accommodate FC disk drives, encryption-capable
FC drives, and SATA disk drives. Intermix of these drive types within the
DS5020 and EXP520 is also supported and adds versatility to these models.

Support for encryption-capable FC drives in the DS5020 and attached EXP520s
is enabled by DS5020 Disk Encryption Activation feature (#7410). Feature 7410
must be installed on the DS5020 to support encryption-capable FC drives in
the DS5020 or EXP520.

Encryption-capable FC disk drives are designed to encrypt data automatically
as it enters the drive to be stored and automatically decrypt the same data
as it moves out of the drive. The embedded encryption engine is designed to
help prevent performance degradation compared with nonencrypting disk drives.

The DS5020 can attach up to six EXP520 Storage Expansion Units, supporting
configurations up to 112 TB physical storage capacity. The DS5020 comes with
a base authorization for use with up to 32 disk drives. This includes support
for the DS5020's internal 16-drive capacity, plus attachment of one EXP520
Expansion Unit. Additional support for up to 112 disk drives and up to six
EXP520 expansion units is available by use of the DS5020 33-64 Disk Drive
Attachment feature (#7393) and DS5020 65-112 Disk Drive Attachment feature
(#7394).

The DS5020 provides further investment protection with the ability to attach
up to six EXP810 Expansion Units. In order to attach the EXP810 Expansion
Unit to the DS5020, the Attach EXP810 to DS5020 Activation feature (#7414)
must be installed on the DS5020. The DS5020 will not operate with EXP810 expansion
units unless feature 7414 is installed.

EXP520 storage expansion unit

The EXP520 (1814-52A) expansion unit is packaged in a 3U rack-mountable
enclosure, contains 16 drive bays, dual-switched 4 Gbps ESMs, and dual power
supplies and cooling components. The EXP520 expansion unit has a physical
storage capacity of up to 16 TB per enclosure using 1000 GB SATA DDMs, and
up to 7.2 TB per enclosure using 450 GB FC DDMs.

EXP520s connect to the DS5020 controller via high-speed 4 Gbps FC disk
expansion ports. The EXP520 has four FC disk expansion ports, and dependent
upon your storage configuration, either two ports or all four disk expansion
ports will be used.

To make use of the disk expansion ports, they must first be populated with
shortwave 4 Gbps SFP transceivers. The first set of two expansion ports are
populated with 4 Gbps SFP transceivers and is used to connect an expansion
unit to the controller or to the last expansion unit in the chain of expansion
units. The second set of two disk expansion ports are populated with 4 Gbps
SFP transceivers using feature 2410, which supplies two 4 Gbps short wave
SFP transceivers. The second set of two disk expansion ports are used on the
last expansion unit in the chain, when attaching an additional expansion unit.
The newly added expansion unit then becomes the last expansion unit in the
chain of expansion units.

As previously stated elsewhere in this section, up to six EXP520 expansion
units can be attached to a DS5020 to provide storage configurations that range
up to 112 disk drives with a physical storage capacity of up to 112 TB using
1000 GB SATA DDMs.

DS5020 storage partitions

The DS5020 has advanced storage management and capacity allocation options.
The DS5020 is designed to enable from two up to 128 storage partitions, to
allocate storage capacity, maximize storage space, and reduce hardware and
storage management costs. Customers must select either 2 (feature #8700),
4 (feature #8701), 8 (feature #8702), 16 (feature #8703), 32 (feature #8704),
64 (feature #8705), or 128 (feature #8706) storage partitions during an initial
plant order of the DS5020. At a later date, if desired, you can chose to field
upgrade to add more storage partitions, up to a maximum of 128 using DS5020
storage partition field upgrade features (#8801 - #8812).

The DS Storage Manager enables management of DS5020 advanced copy services
features such as FlashCopy to instantaneously create capacity-efficient,
point-in-time volume images, providing a logical volume for such uses as file
restoration and backup. In contrast, VolumeCopy creates a complete physical
copy -- or clone -- of a volume within a storage system. This unique entity
can be assigned to any host and used for application testing or development,
information analysis, or data mining.

For attachment to host servers, at least one of the following optional
host kit features must be ordered during initial order of the DS5020 disk
system. The host kits for the DS5020 contain DS Storage Manager and, depending
upon the host kit selected, includes licensed IBM Machine Code to support attachment to
host servers running Microsoft® Windows, System p® running AIX®, or System p running Linux,
Sun/Solaris, HP/HP-UX, and other Intel-based servers.
